Researchers present a way to speed up eccentric effective-one-body models of black hole binary inspirals by averaging away fast orbital oscillations. Inspiral dynamics cost drops by up to two orders of magnitude, overall waveform generation is 1.5-8 times faster, and mismatches stay at or below 8.05e-5.
